Last semester in one of my classes, the professor asked about the the meaning behind a student's shirt. I glanced at it and immediately understood it was a ThunderCats t-shirt. My professor, on the other hand, had assumed it must have been some sort of sports thing.
A brief discussion established that the ThunderCats were smack in the middle of a pop-culture blind spot for our professor. He was too old to have watched the show, and his kids were too young. He had no reason to be exposed to it, and therefore did not understand a symbol that most in our class could instantly identify.

I wonder what kind of pop-culture references I miss simply because I am unaware of them. Often I recognize when a allusion is made that I don't understand. For example, I am 85% likely to not understand a Simpsons reference. My mom didn't like the show and discouraged us from watching it while I was growing up.
What references I do catch are based on more recent exposure, and I'm not sure I really grasp the depth of the cultural bond. It's not something that comes naturally to me, but rather something I've made a conscious decision to be aware of. Am I really participating in the shared cultural understanding if I've only skimmed the Wikipedia article?
I fear I have an even larger blind spot that I'm not even aware of, primarily because most of the friends I've made while at BYU are Mormon. There is a large portion of media that we, as a group, limit our exposure to. This leads to a myriad of things that I don't even realize I don't understand.

I watched the Godfather for the first time a while ago. Suddenly a million little references and quotes and parodies floating around in my head made sense. I did not understand the deep roots this film has in our popular culture until I actually experienced the source material.
So the question is: Am I okay with this lack of understanding? In the last year or so, I've attempted to delve into some of the prolific material that I've previously abstained from. And the thing is, not all of it is worth understanding. Some of it is complete crap. I honestly wish I didn't know why people chuckle when someone says “This one time, at band camp...”

Another example: having noticed several mentions of the new show Archer around the internet, I watched several episodes so I could be conversant in this up-and-coming popular cultural element. And while the show is funny, and people have been taking about it, it's also pretty dirty.
I need to find a balance. How much am I willing to miss out on, culturally? How much am I willing to expose myself to, personally? These are easy decisions to make after the fact; the trick is knowing where the line is before I cross it.
